The .invention relates to straw spreadin attachments for combined harvesting an threshing machines and it is the object of said invention to generally improve upon the construction shown by my U. S.Patent No.

With the foregoing in view, the invention resides in the novel subjectmatter herein after described and claimed, description bee ing accomplished by reference to the accompanying drawings.

Fig. 1 is a side elevation of a combined machine equipped with the attachment.

Fig. 2 is a rear elevation of the attachment disconnected from the machine.

Fig. 3 is a top plan view partly in horizontal section.

Fig. 4 is a vertical transverse sectional view on line 4.4 of Fig. 1.

Fig. 5 is' an enlarged detail side elevation. The form of constructionherein disclosed may be considered as preferred and while this construction will be specifically explained, it isto be understood that within the scope of the invention asclaimed, minor variations may be made. i

'M denotes a combined harvesting and threshing machineprovided near its rear endwith-the usual rattle'rake R. The ma- 0 chine M is provided with an extension E which projects rearwardl-y'beyond the rattle rake R and in this extension a conveyor C is mounted for rearwardly carrying the straw and chaff, received from said rattle rake. One of the shafts S of theconveyor O is driven byv a chain C from'on'e .of the shafts S'of the rattle rake R, and I utilize the shaft S also in driving the straw spread- 'ing attachment hereinafter described. i The attachment embodiestwo parallel longit'udinal bars 5 to be secured by bolts or the like 6 to the sides of the extension Secured to and rising rigidly frortrthe rear ends of the bars 5, are two vertical bars 7 whose upper ends are provided withrearward ly'prlojecting horizontal arms 8., A transverse horizontal shieldboard 9 is secured, to these a arms 8 and two vertical shield boards lOjare secured at their upper ends to said board '9, the inner edges of said boards 1 0 beingfsecured to vertical barsfY. The two shield boards 10- are disposed in a transverse vertical plane.

Two transverse bars 11 and, 1 2 extend between and are rigidly secured to the bars ,5 the-bar 12 being disposed at the rear ends 0 saidbars 5. Bearings '13 are mounted on the transversejbars 11 and 12, said bearingssupporting two parallel longitudinalv shafts 14: whose rear ends are-provided with straw beaters 15 disposed under the shield board Sand behind the boards 7. Additional bearings 1.6. arev mounted on the longitudinal bars 5' for supporting a transverse drive shaft 17 which isoperatively connected by gearing or the like l 8 with the shafts 14, said shafts 17 being driven by a chain 19 and sprockets 20.,

fromthe shaft S above described.

In the preferred'construction, all of the bars 5 7 l1 12 are formed from angle metal and each bar. 5 and-the associated bar 7 are formed by bending, a single length of said metal'jat right angles. I Each right angulalilOend is denoted at 21, and if in making such bend, it be necessary to cut or notch one ofthebar flanges, this weakness is overcome by again welding" the, flange portions to gether. .The two right angular bends 21 are seated within the angle of the rearmost transverse bar l2 and the latter is secured by bolts or the like 22. Certain flanges of thebars 7 preferablyproject laterally outward and i the boards 10 areboltedor otherwise se- P cured against the front sides of these flanges.

Vertical .bar portions .23 preferably lie against the front sides of these boards '10 and at 'their upper ends are integral with the o a arms 8," bolts Q lbeing passed: through said fianges,1said boards and said barportions 23.

. :T-helattacliinent may be'easilyconnectedgq Withthe: machine and when in use all straw rearwardly delivered by the conveyor 0 is effectively distributed bythe-heaters 15. If

itbe desired to savev any chaff falling from the straw before'it reaches these heaters, a reeeptacle such as thatindicatedlat 25 in dotted lines ma be provided.

7 Eiicellent" results have: 'beeniobtained fromthe details disclosed and they are therefore preferably followed. .Attention is again invited tothe factihowever', that within the scope ofthe invention asclaimed, variations -maybemadef J .,-l',claim:-
